6 Reasons for Dye Solar Cells

Good Price/Performance Ratio
Dye solar cells have a good depth in their nanostructure and hence absorb well the photons in the sunlight. Furthermore the dyes used in the cells are efficient in converting the absorbed photons into electrons. The overall peak power-production efficiency of dye-sensitized solar cells is about 11 percent, so they are best suited to low-density applications. Though the efficiency of DSCs is less than many of the best thin-film cells, the price-to-performance ratio obtained through these solar cells is superior to others.

Low Cost
The dye-sensitized solar cells are made of low-cost materials and are cheaper to manufacture. These solar cells do not require any apparatus and can be printed on any flexible surface. Due to the reduced manufacturing costs, DSCs are less expensive when compared to other semiconductor cells.

Ability to Work at Wider Angles and in Low Light
The dye used in dye solar cells can absorb diffused sunlight and fluorescent light. DSCs also work in cloudy weather and low-light conditions without much impact on efficiency, while the other traditional cells would fail at illumination below a certain range. DSCs have a very low cutoff. This makes them suitable for running small devices indoors. These solar cells also work at wider angles, a fact which makes the cells absorb most of the available sunlight.

Long Life
Unlike other thin-film cells, dye solar cells do not degrade in sunlight over time. This characteristic makes the cells last long. They will not require frequent replacements.

Mechanical Robustness
DSCs are mechanically robust. They are made of lightweight materials and require no special protection from rains or trees or any other harsh objects. This makes them easy to use and maintain.

Ability to Operate at Lower Internal Temperatures
As the temperature rises, some electrons in semiconductors are pushed to conduction band mechanically. Hence the silicon cells require protection by covering in a glass box. Such cells get heated easily and hence the efficiency is greatly reduced due to internal temperature. This situation is eliminated in the DSCs. Because dye solar cells are made of only a thin layer of plastic, heat radiates away easily to reduce the internal temperature. This lowering of temperature, in turn, helps in increasing the efficiency of the solar cells.
